Air Zone is one of the most dependable companies I have ever used. We own two houses and have had to use Air Zone on several occasions. They have always been able to come out the same day, which is essential when your air conditioner goes out in the middle of summer in Vegas. Jacob and Brigette, the owners, are great to work with. They are fair, work quickly, and get the job done right the first time. I use them whenever I need air conditioning services and would highly recommend them.
